...Simulation Model Analysis Bouncing Ball Model: Use of Zero-Crossing Detection 2012 Executive Summary In the system of a bouncing ball there are many factors which influence how the ball bounces. The 5 main components which affect how high the ball will bounce include the initial position of the ball, the initial velocity of the ball, the elasticity of the ball, the gravity of the selected area, and also the temperature of the material in which the ball was made from. These 5 major components of the basic system determine how high the ball bounces and how much energy was lost in the process of bouncing as well as allowing us to determine the relationship between these components and how each of these affects the overall system as a whole. However by changing these components of the system, it will dramatically change the overall results. In the system of a bouncing ball there already at secondary school level, illustrates Newton’s laws of motion and concepts of gravitational energy and kinetic energy with examples of objects dropped or thrown vertically and contains investigative activities about falling objects, the physics and mathematics. The fives main components which affect how high the ball will bounce they are initial position, the initial velocity, the elasticity, the gravity and the temperature of the material in which the ball was made from. These five major components of the basic system determine how high the ball bounces and how much energy...

...The rubber from a basketball is made of a large number of rubber strands that all attach at the ends. When the ball hits the floor the many strands become tightly packed by the downwards force (“Why do Rubber Balls Bounce?” n.d., p.1). When bouncing a basketball there is kinetic and potential energy. Kinetic energy has to do with motion. Potential energy is stored energy (“Basketball Bounce Best?” n.d., p.1). As a basketball descends towards the ground, the potential energy turns into kinetic energy (“Physics of Dribbling a Basketball” 2012, p.1). While dropping a basketball the potential energy is caused by its height above the ground. When hitting the floor the kinetic energy turns into sound or heat, causing the ball to temporarily flatten...

...form larger polymers which are normally stronger and more durable. Dissolved in water, sodium borate acts as a binding agent when added to polyvinyl alcohol (PVA), cross-linking the polymers by reacting with the hydroxyl groups in PVA (Baker). When this cross-link occurs, it produces four molecules of water as a byproduct (Figure 1) (“Experiment 2”). Polyvinyl acetate (PVAc) is a rubbery polymer, capable of strong binding and flexibility (Dyslex). PVAc reacts with water, producing acetic acid and a hydroxyl group (Calder). The boric acid from sodium borate reacts with both the PVA hydroxyl groups, and those released from PVAc’s reaction with water (Calder). When combined together in the correct...

...Kyndon Boatman How does a basketball’s bounce change due to surface Research Summary Will the surface affect a bouncing ball- When a ball bounces it uses kinetic and potential. When it is in your hand it is potential when it hits the ground it is kinetic. On average there are 15 dribbles in 1 trip down the court,so dribbling is an important part of the game. If you drop a ball from a set distance and it is regulation air pressure on a gym wood surface it will bounce back up ⅔ of the height you dropped it. When a basketball hits the ground (and as it flies through the air), it actually transforms some of its energy to another form. If players do not put enough energy back into the ball, they will not be able to dribble it effectively. Some...

...The Ryerson Rams men’s soccer team have punched their ticket to the Final Four. This comes after the team beat up on the Carleton Ravens in their quarter final game on Sunday at Downsview Park. It didn't take the Rams long to get on the scoring sheet. In the seventh minute captain Martin Dabrowski controlled a bouncing ball and sent a perfect through ball to Nick Lambis who put it past the Carleton Keeper and giving the Rams the early lead. Ryersons style of play this game was considerably different rather than maintaining ball possession they focused on getting shots on the net. “ It was a little more direct a little more no nonsense, get the ball to the striker, get the ball forward and create chances,” said coach Prostran.

...shapes in a display area. The programming assignment for this week is to implement a simple paddle ball game. Paddle Ball Game Overview The paddle ball game is a simplification of the Pong game. In the Pong game, a ball is moving around the display, bouncing off walls. The player moves a paddle in one dimension, trying to hit the ball whenever possible. If the ball hits the paddle, it bounces off and continues on its way. If the paddle misses the ball, the ball goes off the end of the display area and the player loses a point. In our paddle ball game, the ball moves around the display, bouncing off walls just as in the Pong game. The player controls a paddle trying to hit the ball just like in the Pong game. If the ball hits the paddle, it bounces off and continues on its way. The main difference in our game is that if the player misses the ball, the ball simply bounces off the wall behind the paddle and continues to travel. There is no scoring in this game. Object Oriented Design If we analyze the game description we can see there are several different objects which are interacting. There is a ball object which is traveling around the display. There is a paddle object which is being moved by the player. There is a display which is presenting the graphical representation of the game to the user. These objects are readily apparent from the description of the game. The ball object has a size and a position within the field of play. It also has a...

Just like the fans the opponents were also scared all their hard work could be lost with this one shot. As the young man’s heart is racing he knew the spotlight would rest on him with 1 minute left. Within a madder of second’s fans, players and coaches had become silent as the final timeout was called. The only thing to be heard in the building was the sound of pen and players agreeing. Deshawn’s heart was pounding as he knew that he hadn’t got a single shot to fall. As the game went on his shots wear bouncing off the rim, air balling or even being blocked. He couldn’t buy a shot.

...Putty "Stretch it, pull it, Bounce it" (Ball of fun) Introduction: Silly putty is a toy that kid totally enjoy or chemical compound made of silicone and boric acid. It is composed of flexible molecules that give the material flow. Silly putty is a viscoelastic liquid and is a mixture of water, glue, and boron [1]. The word, viscoelastic is a compound word, visco means "resistant to flow" [Dictionary] and elastic describes a material that when stretched returns to its original form. In silly putty, each molecule is made of long chain of identical smaller molecules. When boric acid is applied to these long chains, boron cross-links begin to form [1]. Because of the constant motion of the molecules in solids and liquids, the boron cross-links are not very strong and break very easily. Silly putty react different to quick and slow forces [1]. When one quickly stretches it, it breaks instantly, and if one stretches it slowly it will stretches to greater distance and then breaks at some point. One can bounce it, throw it, decorate with it, stretch it, or make imprints with it. Uses: 1. Pen Grip – The hard surfaces of pens and pencils can cause calluses, especially if we write for long periods. we can cover the pen’s gripping point with a layer of silly putty. It will cushion fingers [2]. 2. Contact Lens Finder – Finding transparent contact lenses on the floor is challenging. They naturally blend with their surroundings. One can roll a ball made of silly putty on the floor [2]...

...My Speech – Gaelic 1 Introduction Hello, for my hobby I have chosen Gaelic football. Which is the most popular sport in Ireland, It is played throughout every county in Ireland but is also played in America and England. Gaelic football belongs to an association that also includes, Hurling and Irish handball this is formally known as the Gaelic athletic association but for short the GAA. 2 detail The all-Ireland football trophy is called the Sam Maguire cup and was recently won by a Kerry side as a result of beating Donegal in the final 2-9 to 0-12. Kerry have won the all-Ireland 37 times which is more than any other county. Also quite recently The GAA has been broadcast across the UK and other countries thanks to sky sports. This has been great for the sport in my opinion as it spreads the popularity of the sport in countries which have probably never heard of it. 3 What is Gaelic? What is Gaelic? Well… Gaelic is a fast-paced game between 30 players on a field larger than a football pitch. The object of the game is to put the ball in your opponents net for a goal which worth three points or, failing that, between the posts and above the crossbar for one point. Matches last for 60 minutes at senior level but at my age group 40 minutes, you use a ball similar to a soccer ball, which you can either kick or hand-pass 4 Involved I got involved in the sport from a young age as my family also played it when they were young. My Dad played for county, Antrim and...

...In this episode of the Brain Games, I learned a lot about how color and perception can trick our brains. In Game #1, my brain made me see the ball as rolling, taking off, and bouncing up and down even though the only change in the movements was the shadow. As said in the show, we have become so used to one light source, we have learned to trust or perception of shadows. As I learned in the episode, not only can shadows lie to you, but colors can also lie to you. Game #2 showed two sides of a box with one side that seems to have a shadow over it. One square on the box looked completely different from the other, but was exactly the same. Along with this, Game #3 showed a soccer ball and a golf ball. I thought the soccer ball was larger, but...
